1. A display substrate, comprising:
a base substrate;
a first signal transmission line on the base substrate and comprising a first transmission sub-line and a second transmission sub-line side by side in a same layer and electrically connected to each other;
a first insulating layer on a side of the first signal transmission line away from the base substrate;
a second signal transmission line on a side of the first insulating layer away from the base substrate and being in direct contact with the first transmission sub-line through a first via extending through the first insulating layer;
a second insulating layer on a side of the second signal transmission line away from the base substrate; and
a first connection member on a side of the second insulating layer away from the base substrate, connected to the second signal transmission line through a second via extending through the second insulating layer and connected to the second transmission sub-line through a third via extending through the first insulating layer and the second insulating layer.
